In this session recorded at Unreal Fest Bali 2025, Alexis Argyriou of The Bureau Consulting walks you through his work on ‘BADMAD ROBOTS’, a modern hero shooter releasing in 2025.
Hear the tale of how he raised performance on modern GPUs from 22 fps to over 120 fps— without loss of visual quality—and built systems to scale down all the way to run on last-gen laptop chipsets.
He reveals his “hack” to run Lumen on high-end devices and switch back to pre-baked lighting for low-end devices; the challenges he encountered in dealing with static lights in Lumen; how he creatively dealt with overlapping stationary lights and hidden VFX costs; and how to carefully monitor GPU performances using Unreal Engine’s built-in profiling tools like Unreal Insights.
